Which of the following is equal to C(10, 3)?
C(3, 10)
C(10, 7)
P(10, 3)
Answer:
P
Step-by-step explanation:
C and P are both (10,3).
Presumably C(10,3) refers to the combinations of 10 things taken three at a time, often written
[tex]\displaystyle {10 \choose 3}[/tex]
When we choose three of 10, we're actually also choosing seven of 10, the leftovers. So there are the same number of combinations of three as combinations of seven. In general
[tex]\displaystyle {n \choose k}={n \choose n-k}[/tex]
Answer: C(10,7)
which expression is not equal to 1
The only option that is not equal to 1 is sinθcosθ
Acoording to trigonometric identity

Complete the equation and solve the problem. Let n be the number of students in each row. There are 37 students in the marching band. There are 5 students in the first row, and the rest are in 4 equal rows. How many students are in each of the 4 rows?
Answer:
37 - 5 = 32
32/4 = 8
8 students are in each of the 4 rows
Answer: there are 8 students in each of the 4 equal rows
Step-by-step explanation:
x = # of students in each of the 4 rows
4x + 5 = 37
4x = 32
x = 8
There are 8 students in each of the 4 rows.
You can check this:
4 rows of 8 students —> 4(8) = 32 students
+ 5 students in the first row
= 37 students total

4) Gina pays $0.50 each time she plays a carnival game. The game is on a spinner with 12 equal-sized sections, labeled 1 through 12. She wins a prize if the pointer lands on 3, 5, or 7. If Gina spends $4 playing the game, predict the number of prizes she can expect to win.
Answer: 2 prices
Step-by-step explanation:
Price per play = $0.50
Total amount incurred by Gina in playing =$4
Therefore, total games played :
$4 ÷ $0.5 = 8 games.
Total points on spinner = (1,2,3,4,5,6,7,8,9,10,11,12)
Required for winning = (3, 5, 7)
Probability of winning:
P(WIN) = ( required outcome / Total possible outcome)
P(win) = 3/12 = 1/4
Therefore, the number of prices she can expect to win is (1/4) × number of games (8)
(1/4) × (8) = 2

an online store randomly assigns shoppers a confirmation code after making a purchase. the confirmation code consists of 4 letters followed by 3 digits. within the confirmation code, letters can be used only once but digits can be repeated. how many different confirmation codes are possible?
A. 14,950,000
B. 5,311,735
C. 358,800,800
D. 358,800
Answer: C. 358,800,800
Step-by-step explanation:
Total digitrs ( from 0 to 9 ) = 10
Total letter ( from a to z ) = 26
To make the code , we require 4 letters followed by 3 digits .
If letter can be used once ( i.e. repetition is not allowed) , then the number of ways to arrange this sequence of letters = [tex]^{26}P_4[/tex] [By using Permutation]
[tex]=\dfrac{26!}{(26-4)!}=\dfrac{26\times25\times24\times23\times22!}{22!}[/tex]
[tex]=26\times25\times24\times23=358800[/tex]
But repetition is allowed for digits , so number of ways to arrnge 3 digits = [tex]10\times10\times10=1000[/tex]
Now , the total number of ways tio make the code = 358800 x 1000
=358,800 ,000
Hence, the correct option is C. 358,800,800.

The area A of a trapezoid is the height h times the average of the parallel bases a and b.
A = (1/2)(a + b)h
Solving for a,
2A = (a+b)h
2A/h = a+b
a = 2A/h - b
We have A=59.64, b=4, h=8.4
a = 2(59.64)/8.4 - 4
a = 10.2 yards

At a store, a hat has a regular price of x dollars. During a sale, the price of the hat is discounted by 20%. The expression 0.8x describes the discounted price, in dollars, of the hat. Which expression also describes the discounted price, in dollars, of the hat? A. 0.2x
B. x–20
C. x–0.2
D. x–0.2x
Can someone explain why is D correct ?
Answer:
Step-by-step explanation:
x-.20x
Lets say the hat cost $100
x=100
multiplying 100 by 20% which is .20 yields $20
S0 $20 is the discount which we subtract from the original price
100-20 and get the sale price of $80
They use a shortcut so you don't have to do the subtracting of the discount
They say if the price is being discounted subtract the discount from 1 and multiply that by the original amount
So in this case the discount percent was 20% = .20
Subtracted from 1
1-.20=.80
Since x is the original price we multiply x by the .80 to get
.80x

2x + 8y = 21 6x - 4y = 14
Step-by-step explanation:
{2x+8y=14
{216x-4y=14
{x+4y=7
{216x-4y=14
217x=21
x=3/31

Greg has a bag that contains 25 colored tiles. Of all the tiles in this bag, 10 are blue. Suppose another bag contains 250 colored tiles. Of all the tiles in this bag, 75 are blue. From which bag is Greg less likely to pick a blue tile? Explain.
Answer:
he is less likely to pick a blue tile in the second bag
Step-by-step explanation:
divide 10 by 25 which will give you 40%
divide 75 by 250 which will give you 30%
this makes it less likely for Greg to pick blue from the second bag, as the first bag has a higher percentage chance

A package of books weighs 72 ounces. What is the weight of the package in pounds?
Answer: 4.5 pounds
Explanation: To convert 72 ounces into pounds, we use the conversion factor for ounces and pounds which is 16 ounces = 1 pound.
Next, notice that we're going from a smaller unit, ounces, to a larger unit, pounds and when we go from a smaller unit to a larger unit, we divide. So here, we divide 72 by the conversion factor, 16, to get 4.5.
So 72 ounces equals 4.5 pounds.
Timothy makes reduced copies of a photograph that has an actual length of 8 in. Each time he presses the reduce button on the copier, the copy is reduced by 12%. What formula shows the pattern for the size of each copy of the photograph as it is reduced? What is the length of the photograph’s copy if Timothy presses the reduce button 5 times? Round to the nearest tenth.
Answer:
length of the photograph will be 4.2 in. after pressing the button 5 times.
Step-by-step explanation:
By pressing the button, every time size of the photograph gets reduced by 12%.
Therefore, the sequence formed by the reduced sizes of the photo will be a geometric sequence and the formula for the size of the reduced image will be,
L = [tex]l(1-\frac{12}{100})^{n}[/tex]
Where l = Actual length of the photograph
L = length of the reduced image
n = Number of times the button has been pressed
For l = 8 in. and n = 5
L = [tex]8(1-0.12)^{5}[/tex]
= [tex]8(0.88)^{5}[/tex]
= 4.22 in
L ≈ 4.2 in.
Therefore, length of the photograph will be 4.2 in. after pressing the button 5 times.
The length of the photograph's copy when the button is pressed the 5th times is 4.2 inches
The question is an illustration of an exponential function.
An exponential function is represented as:
[tex]y = ab^x[/tex]
Where:
a represents the initial value i.e. a = 8b = 1 - r; and r represents the rate. i.e. r = 12%.So, the function becomes
[tex]y = 8 \times (1 - 12\%)^x[/tex]
Express 12% as decimal
[tex]y = 8 \times (1 - 0.12)^x[/tex]
This gives
[tex]y = 8 \times 0.88^x[/tex]
When the button is pressed the 5th times, we have:
[tex]y = 8 \times 0.88^5[/tex]
[tex]y = 4.2[/tex]
Hence, the length of the photograph's copy is 4.2 inches

You have money in an account at 6% interest, compounded monthly. To the nearest year, how long
will it take for your money to double.
Answer:
Step-by-step explanation:
Let amount now be x , meaning principal is x
and the amount later A is 2x
A = P(1+r/n)^nt
n = 12
2x = x (1 + 0.06/12)^12t
divide through by x
2 = (1+ 0.005)^12t
2 = (1.005)^12t
Take log of both sides
log 2 = 12t log 1.005
12t = log2/log 1.005
12t = 138.975721610697
t = 138.975721610697/12
t = 11.58
t = 12 years

Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answer: $6.62
Step-by-step explanation:
This problem is very similar to the one I answered previously. We are given our p, r, and t.
p=6 ($6)
r=0.05 (5%)
t=2 (years)
With the given information, we can plug this into the equation:
B=p(1+r)^t
B=6(1+0.05)^2
B=6.615
Our final amount is $6.62.

Factoring expressions: 17x-34xy
17x(1-2y)
17x-34xy
because both expressions have a x, it would be easier to factor out the x first. but because 17 is a factor of 34 you can simply divide 34 by 17 and get 2. so you put it together to this,
17x(1-2y)
Because, 17x times 1 is 17x but 17x times -2y would be -32xy.
Answer:
17x(1-2y)
Step-by-step explanation:
1) so "x" is common in this expression so lets take that out first:
x(17-34y)
2) but 17 is also common since 17*2=34 so lets take "17" out:
17x(1-2y)
